Abstract

Purpose

The purpose of this research paper is to compare corrosion data obtained from additive-manufactured heat-treated (HRx) and non-heat-treated (NHRx) cobalt-chromium (Co–Cr) alloys. Heat treatments are indicated as necessary in complex intra-oral framework production by additive manufacturing to remove accumulated thermal stresses. However, heat treatments have been linked to corrosion in cast dental alloys. Currently, there are few publications on this subject for laser-sintered dental alloys required for academic review.

Design/methodology/approach

Five rectangular specimens (n = 5), each with a total surface area of 10.27 cm2, were fabricated for the two groups. Specimens were immersed in an artificial saliva solution suspended by a nylon thread for 42 days at 37°C. Readings for Co, Cr and molybdenum ions released into the solution were obtained using an atomic absorption spectrometer at 1-, 4-, 7-, 14-, 21-, 28-, 35- and 42-day intervals at a detection limit of one part per million. Test methods are in accordance with ISO 10271.

Findings

Results showed a higher ion release in the HRx sample, statistically significant at 99 per cent confidence level (p < 0.01). A two-way ANOVA test conducted showed that there was a main effect of day and a main effect of finish, and there was also a significant interaction between these factors.

Originality/value

The study concludes that, although ion release in both samples was within the safe level recommended by ISO for the three major alloying elements, heat treatment, indeed, contributed extensively to the reduced corrosion resistance in the laser-sintered Co–Cr alloy. Further biocompatibility tests are recommended.

Abstract

This research provides accounting-ethics authors and administrators with a benchmark for accounting-ethics research. While Bernardi and Bean (2010) considered publications in business-ethics and accounting’s top-40 journals this study considers research in eight accounting-ethics and public-interest journals, as well as, 34 business-ethics journals. We analyzed the contents of our 42 journals for the 25-year period between 1991 through 2015. This research documents the continued growth (Bernardi & Bean, 2007) of accounting-ethics research in both accounting-ethics and business-ethics journals. We provide data on the top-10 ethics authors in each doctoral year group, the top-50 ethics authors over the most recent 10, 20, and 25 years, and a distribution among ethics scholars for these periods. For the 25-year timeframe, our data indicate that only 665 (274) of the 5,125 accounting PhDs/DBAs (13.0% and 5.4% respectively) in Canada and the United States had authored or co-authored one (more than one) ethics article.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

Blues music is in the midst of its second revival in popularity in roughly thirty years. The year 1960 can be identified, with some qualification, as a reference point for the first rise in international awareness and appreciation of the blues. This first period of wide‐spread white interest in the blues continued until the early seventies, while the current revival began in the middle 1980s. During both periods a sizeable literature on the blues has appeared. This article provides a thumbnail sketch of the popularity of the blues, followed by a description of scholarly and critical literature devoted to the music. Documentary and instructional materials in audio and video formats are also discussed. Recommendations are made for library collections and a list of selected sources is included at the end of the article.

Abstract

Middle level teachers, at times, link historical content with relevant English literature in interdisciplinary units. Elementary teachers periodically employ history-themed literature during reading time. Interconnections between language arts and history are formed with developmentally appropriate literature for students. Historical misrepresentations, however, proliferate in children’s literature and are concealed behind engaging narratives. Since literacy and historical thinking are essential skills, children’s literature should be balanced within, not banished from, the classroom. Using America’s peculiar institution of slavery as a reference point, this article examines children’s literature, identifies almost a dozen areas of historical misrepresentation, and proffers rich primary source material to balance the various misrepresentations. We provide teachers with reason for caution when including such literature; but also model how to locate, use, and, at times, abridge primary source material within an elementary or middle level classroom. Such curricular supplements provide balance to engaging but historically-blemished children’s literature and enable educators to attain the rigorous prescriptions of Common Core.

Abstract

Alvin Hansen and John Williams’ Fiscal Policy Seminar at Harvard University is widely regarded as a key mechanism for the spread of Keynesianism in the United States. An original and regular participant, Richard A. Musgrave was invited to prepare remarks for the fiftieth anniversary of the seminar in 1988. These were never published, though a copy was filed with Musgrave’s papers at Princeton University. Their reproduction here is important for several reasons. First, it is one of the last reminiscences of the original participants. Second, the remarks make an important contribution to our understanding of the Harvard School of macro-fiscal policy. Third, the remarks provide interesting insights into Musgrave’s views on national economic policymaking as well as the intersection between theory and practice. The reminiscence demonstrates the importance of the seminar in shifting Musgrave’s research focus and moving him to a more pragmatic approach to public finance.
